I am looking for some Splus or R code to do a
FROC analysis, in particular
a comparison of the diagnostic ability of two
groups. From what I have been able to glean from the couple
of papers that my radioligist consultee has given
me to read, FROC stands for "Free Response ROC",
and it arises in
radiology where the screener may find none, one, or more than one
abnormality, and rates each of them. This
distinguishes it from the case where ROC
analysis is popular, where the unit of measurement
is the X-ray or image.
I am open to other approaches as well.
Thanks
